DESIGN IDEAS Triple Output TFT-LCD Bias Supply
Uses All Ceramic Capacitors by Gary Shockey
Current power supply requirements for TFT-LCD panels call for an
8V or 10V main supply plus two or
more auxiliary outputs. The overall
layout must be small and meet tight
height requirements of under 2mm.
Bulky inductors and capacitors must
be eliminated if the design is to meet
space requirements. The circuit described in this design idea features
the new LT1949 and delivers 8V at
200mA from 3.3V while generating
auxiliary 24V and вЂ“8V outputs capable
of 10mA of output current.
The LT1949 is a boost switching
regulator that comes in the MSOP-8
package and has an integrated 1.1A
NPN power transistor. For this appliD1 VOUT
